Unit 6: 2-D Geometry and Patterning
Learning Goal: we will have a strong understanding of 2-D geometric figures, symmetry, and patterns.
Success Criteria: we know we are successful when we are able to...
Success Criteria: we know we are successful when we are able to...
- describe, sort, and compare 2-D figure according to the numbers of side and numbers of vertices
- recognize figures that have symmetry, or matching parts.
- make patterns using materials and pictures of 2-D figures.
- Use positional language to describe movement and location: slide to the left, turn, above, beside.
Comparing 2-D Figures: Sides and Vertices
To compare our different figures/shapes, we will look at two attributes to determine the difference between the shapes. These two attributes are sides and vertices. In our class, we define a side as any line which connect two vertices. A vertex (plural is vertices) is a point where two lines meet.

Symmetry
Geometric Figure Movement - Flip, Slide, Turn
Flip: to turn a shape over creating a mirror image. This is when you would see examples of symmetry.
|
Slide: to move a shape without rotating or flipping it. The shape looks exactly the same, just in a different place.
|
Turn: A circular movement. Rotation has a central vertex that stays fixed and everything else moves around that vertex in a circle.
